SAMUEL I. BERGER, OF NEWARK, NEW JERSEY.

BRAKE FOR 'roY Morons.

Application filed August 16, 1924. Serial No. 732,518.

This invention relates to motors such as are used for mechanical toys; and it is an object of my invention to provide a simple brake. therefor with a minimum of parts.

It is also an object of my invention to provide such an arrangement of brake and motor in a toy as will facilitate the assembly thereof.

One embodiment of my invention is illustrated in the drawings in which 2- Fig. 1 is a plan View looking upwards of a portion of a toy with the motor and brake in position.

Fig. 2 is a cross sectional view taken on the line 22 of Figure 1, and looking in the direction of the arrows.

I have shown my brake applied to a motor such as is shown in Patent Number 1,893,936, granted to me October 18th, 1921; but it is clear that any other suitable motor may be used instead.

1 is a shaft which is mounted at one end in a partition 5, extending the width of the toy. The other end of the shaft 1 is frictionally engaged with ratchet wheel 2. A

winding handle 4 is connected to the ratchet wheel 2; and a pawl 52 is mounted in the casing, all in the manner shown in my patent aforementioned. A spring 3 surrounds the shaft 1, and has'one end connected to the ratchet wheel 2, and one end connected to the shaft. A gear 6 is fixed to the shaft 1 and drives a train of gears 7. A partition 8 cooperates with partition 5 to support the train of gears. Shafts 9 and 10, mounted in partitions 5 and 8, are connected to mech anisms (not shown) for imparting motion to various parts (not shown) of the toy. A

plate 11 partly covers the bottom of the toy.

The gear train 7 has a final member 12,

which is adapted to cooperate with the brake 13. I 1

The brake 13 is shaped out of a straight flat bar of metal and has two substantially parallel portions 1 1, 15, and a short portion 16, at an angle thereto connecting the portions 14 and 15. The portion 15 extends through a narrow slot 17in a side wall 18 of the toy, and is provided at its end with a curved over portion 19, which serves as a 0 handle or grip. The portion 16 passes through a slot in the wall 11, which has sufficient clearance to permit the portion 16 to act as a pivot for the brake and permit of the brake being moved from the full-line to 5 the dotted line position shown in Figure 1, and vice-versa. The portion 14 extends along the plate 11, over the partition 8 and is adapted to be engaged with a tooth of gear 12 to hold that and the rest of the 0 mechanism stationary.

WVhen the toy is assembled, the end of the brake is slipped through the slot in the plate 11 until the portion 16 is engaged with the slot. The step 16 cooperates with the wall 11 to prevent refraction of the brake. The brake may then be moved sideways about an axis perpendicular to plate 11, and about 16 as a pivot. The end of portion 14 is cut away as at 20 in order to facilitate assembly 7 and. reduce the clearance necessary around gear 12.

I claim:

In a motor, a brake consisting of a stepped bar having a substantially rectan- 7 gular cross-section, having two arms and a connecting step, and a supporting plate having a slot engaged with the step, the slot V having clearance sufiicient to permit slight oscillation of the brake.

Signed at Newark in the county of Essex and State of New Jersey this 13th day of August A. D. 1924.
